CIRCUIT TECHNOLOGY
General Description
The Aeroflex Circuit Technology
ACT 4433 is a next generation
monolithic
transceiver
design
which provide full compliance to
MIL-STD-1553A/B and 1760 re-
quirements in a smaller package
with lower pin count then the
ACT4489D, for those designs with
less board space.
The ACT 4433 series performs
the front-end analog function of
inputting and outputting data
through a transformer to the
MIL-STD-1553 data bus.
Design of this transceiver reflects
particular attention to active filter
performance. This results in low bit
and word error rate with superior
waveform purity and minimal zero
crossover
distortion.
Efficient
transmitter electrical and thermal
design provides low internal power
dissipation and heat rise at high as
well as low duty cycles.
Transmitter:
The Transmitter section accepts
bi-phase TTL data at the input and
when coupled to the data bus with a
1:1 ratio transformer, isolated on
the data bus side with two 52.5
Ohm fault isolation resistors, and
loaded
by
two
70
Ohm
terminations, the data bus signal is
typically 7 Volts P-P at point A (See
Figure 5). When both DATA and
DATA inputs are held low or high,
the transmitter output becomes a
high impedance and is “removed”
from the line. In addition, an
